About this trial

Hemophagocytic lymphohistiocytosis is a rare, aggressive and life-threatening syndrome of excessive immune activation. Secondary hemophagocytic lymphohistiocytosis (sHLH) is the most common form of this disease and is typically associated with several other clinical conditions (eg, malignancy associated HLH (mHLH), infection, or autoimmune disease). ELA026 is a fully human immunoglobulin G1 (IgG1) signal regulatory protein (SIRP)-directed monoclonal antibody designed to deplete the myeloid and T cells driving the inflammation. The purpose of this study is to assess the safety, efficacy pharmacokinetics and pharmacodynamics of ELA026 in participants with sHLH.

Eligibility criteria

Qualifiers

Disqualifiers

Known or previous treatment for primary HLH

Any other significant concurrent, uncontrolled medical condition that in the opinion of the Investigator contraindicates participation in this study

Unknown trigger for sHLH

Active, relapsed/refractory malignancy for which no suitable therapies are available to treat the malignancy triggering the HLH
